Phosphoroteomics analysis of ALK signaling in neuroblastoma cells

ABSTRACT: We used mass spectrometry-based proteomics to unravel anaplastic lymphoma kinase (ALK) signaling in the ALK and MYCN amplified neuroblastoma cell line, NB1. We specifically measured the ALK phosphoproteome upon siRNA depletion of ALK and upon ALK inhibition using the ALK-targeting small-molecule inhibitor lorlatinib. For quantitative phosphoproteomics we used a tandem mass tag (TMT)-based approach. Conditions for the TMT 11-plex setup is specified below. For each siRNA depletion experiment, NB1 cells were treated with siRNA (80 nM; as specified below) for 48 hours prior to stimulation with 0.1% DMSO for 30 minutes. For inhibitor treatment, NB1 cells were treated for 30 minutes with either 10 microM or 10 nM lorlatinib. The experimental treatment conditions and TMT11-plex labeling are specified below: 126: siControl replicate 1, 0.1% DMSO 127N: siControl replicate 2, 0.1% DMSO 127C: siControl replicate 3, 0.1% DMSO 128N: siALK sequence 1, 0.1% DMSO 128C: siALK sequence 2, 0.1% DMSO 129N: siALK mix of sequence 1 and 2, 0.1% DMSO 129C: 10 microM lorlatinib replicate 1 130N: 10 microM lorlatinib replicate 2 130C: 10 microM lorlatinib replicate 3 131N: 10 nM lorlatinib replicate 1 131C: 10 nM lorlatinib replicate 2

Oncogenic anaplastic lymphoma kinase (ALK) is one of the few druggable targets in neuroblastoma, and therapy resistance to ALK-targeting tyrosine kinase inhibitors (TKIs) comprises an inevitable clinical challenge. Therefore, a better understanding of the oncogenic signaling network rewiring driven by ALK is necessary to improve and guide future therapies. Here, we performed quantitative mass spectrometry-based proteomics on neuroblastoma cells treated with one of three clinically relevant ALK T ...[more]

Project description:We used mass spectrometry-based proteomics to unravel anaplastic lymphoma kinase (ALK) signaling in the ALK and MYCN amplified neuroblastoma cell line, NB1. We specifically measured the ALK interactome, phosphoproteome, phosphotyrosine interactome and proteome as outlined below. ALK Interactome and phosphoproteome: For each experiment, three SILAC conditions (‘Light’: Lys0,Arg0, ‘Medium’: Lys4,Arg6, ‘Heavy’: Lys8,Arg10) of NB1 cells were treated for 30 minutes with each of the following ALK-targeting small-molecule inhibitors: TAE684 (100 nM), crizotinib (500 nM), and LDK378 (250 nM). The experiments were performed as specified below: Experiment 1: Light: 500 nM crizotinib, Medium: 100 nM TAE684, Heavy: 0.1% DMSO Experiment 2: Light: 100 nM TAE684, Medium: 250 nM LDK378, Heavy: 0.1% DMSO Experiment 3: Light: 250 nM LDK378, Medium: 500 nM crizotinib, Heavy: 0.1% DMSO These three triple-SILAC experiments allowed the effect of each inhibitor to be measured in duplicates. ALK phosphotyrosine interactome: To identify phosphotyrosine-specific interaction partners of ALK we used a label-free mass spectrometry-based proteomics approach. Interacting proteins to the peptide sequences (phosphorylated and non-phosphorylated peptide) indicated in the table below were identified by a peptide pull-down assay and mass spectrometry. Peptide pull-downs were performed on NB1 cell lysate prepared from cells treated for 30 minutes with LDK378 (250 nM) or DMSO. Each peptide pull-down was performed on lysates from two biological replicates.

Project description:Mass spectrometry-based proteomics was applied to unravel Erk signaling in mouse embryonic stem cells (ESCs). A previously described engineered ESCs system for Erk induction via a drug-inducible cRAF-ErT2 fusion (Hamilton, W. B. & Brickman, J. M., Cell Rep 2014) was used in two different setups measuring the phosphoproteome in an 11-plex tandem mass tag (TMT)-based approach as described below. Fgf4 stimulation and MEK inhibition: ESCs were stimulated with Fgf4 (40 nM, recombinant, mouse, 5 minutes) following pretreatment (30 minutes) with either DMSO (1:10000) or MEK inhibition (MEKi: 1 microM PD0325901): The experimental treatment conditions and TMT11-plex labeling are specified below: 126: DMSO, unstimulated control replicate 1 127N: DMSO, unstimulated control replicate 2 127C: DMSO, unstimulated control replicate 3 128N: DMSO + Fgf4 replicate 1 128C: DMSO + Fgf4 replicate 2 129N: DMSO + Fgf4 replicate 3 129C: MEKi + Fgf4 replicate 1 130N: MEKi + Fgf4 replicate 2 130C: MEKi + Fgf4 replicate 3 131N: MEKi replicate 1 131C: MEKi replicate 2 Analog sensitive Erk2 setup: In the ESC system the ERK2-/- ESCs (Hamilton et al., PloS ONE, 2013) were engineered to stably express an inducible cRAF-ErT2 fusion protein expressed from the same transgene as a FLAG-tagged analogue sensitive Erk2Q103A. Erk1 was subsequently removed by CRISPR-Cas9 mutagenesis using sgRNAs flanking exon 2. Cells were pre-treated for 30 minutes with either the ATP-mimetic compound 1-NM-PP1 (2 microM) (Endo et al., Biochem Biophys Res Commun 2006), the Mek1 inhibitor PD0325901 (1 microM), or DMSO (0.01%), followed by induction or not of the cRAF-ErT2 fusion by (Z)-4-Hydroxytamoxifen (4OHT) (250 nM) for 2 hours as indicated.
